Exam 2: Information Management and It Architecture

Storage virtualization is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console.

The mass migration of users from PCs to mobile devices has expanded ISs beyond the organization and made human employees increasingly irrelevant.

When making decisions about how to acquire hardware, software, or any other components of the IT Infrastructure, the following four characteristics of an IT infrastructure need to be considered: -Dependable -Manageable -Adaptable -Affordable Evaluate cloud computing solutions on each of these four criteria and explain why it has become an increasingly attractive option for many organizations.

In an effort to free themselves from the burden of deploying, provisioning and updating software apps, many companies are turning to _______________________.

Which of the following is one of the 4 components of IT Architecture described in your text?

When transactions are typically processed as each transaction occurs, it is called "real-time processing".

The most potentially valuable type of information for managers comes from large collections of transaction records which can be analyzed for patterns of financial performance.

Companies or government agencies that need greater security and data confidentiality set up their own clouds on servers that they own. These are called "protected clouds".

The functional difference between a DSS and an MIS is that a DSS contains models that use information to make decisions while an MIS is used to create reports from data.

A _______________________ is an interactive application that aids managers in making decisions that would otherwise require a great deal of time to figure out.

_______________ refers to a process of changing assumptions or data in a model to see how the changes impact the predicted outcome.

Databases and data workers, information management personnel and networks are all considered parts of an organization's IT infrastructure.

The term _______________ ____________refers to how information is stored and organized; and the speed at which it is captured, analyzed, and reported.
